SPECIFIGATIQN forming part of Letters Patent No. 699,075, dated April29, 1902.

Application filed October 7, I901, SerialNo. 77,778. (No model.)

T0 all'whoml it may concern:

Be it known that I, SHARON CASE, a citizen of the United States,'and aresident of Mon tures in the appended claims.

Reference is tobe had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of adnplicatorembodying my invention.vFig. 2"i s' a longitndinalsection thereof. Fig. 3 is a simi-- larsection, but showing a'different'manner of arranging the paper strips.Fig. dis a section showing a modification as to the length of thedevice. the carbon-sheet holder,and Fig.6 is a perspective view showingthe bed-plate and rollholding frame.

The device comprises a casing 1, of any suitable material, butpreferably nletal, and

having swinging connection with this casing is a cover 2. At its hingeend the cover has of the rear end of the box orcasing, and these earsare attached to a shaft 4,-which extendsthrough the casing. One end of acoiled spring 5 is attached to said shaft, theother end of said springbeing attached to the cas ing, and this spring is designed to swing theadapted'to engageits upper hook end with a latch-plate 7 on the cover.

The removable bed-plate 8, over which the Fig. 5 is a perspective viewof is removed.

paper strips pass, is provided with downwardly-extended sides 9, thatfit closely against the inner sides of the side walls of the 'casing,and these side portions 9 are provided with indentations 10, which formbearings for -the'wires or spindles on which the paper rolls 11 and'12are mounted. It is to be understood that two strips of paper fromseparate rolls are to be drawn over the bed-plate,

and placed between the two strips over the bed-plate is a carbon ortransferring sheet 13. Therefore by writing with a pencil or the like onthe upper strip of paper the writing will be transferred by the carbon-sheet to the lower strip. a

The carbon-strip is held in place and pre- :vented from outward movementwith the strips of paper by means of a frame 14, which has side flangeslo, designed to, press the edges of the carbon-sheet downward betweenthe side portions 9 of the bed-plate frame and the side walls of thecasing.

While it is designed that paper from-two rolls only shall be used at onetime, in Fig. 2 I have shown four rolls. This is merely for convenience,as after two rolls shall have been used up theother twomay be quicklyput inuse. In Fig. 3-the two strips of paper, however,- instead'of beingplaced in rolls are folded back and forth, one layer upon another.

- Th'e devices shown in Figs. 4, 5, and 6 are similar in all respects tothe devices described in'connection with Figs. 1 and- 2, excepting thatthey are made considerably shorter and .rbu't tw'drolls are used.

" In insertingnew rolls of paper the frame 14 is to be first removed.Then the bed-plate The side walls 9 will yield sufficiently to permitthe spindles to pass into the depressions. After this the parts are tobe again assembled. It will be noted that the two paper strips pass outof the end of the casing between the end bar of the frame lat and thetop of the end-wall of the casing, and

when drawn out they may be readily torn ofi, having projected ends to beeasily grasped with the hand. a

It will be understood that the device may be made of such size as to beadapted for counter use.

Having thus described my invention, I tended side portions which fitagainst the inclaim as new and desire to secure by Letters ner sides ofthe side walls of the casing, and
